The quality of a decision is kind of an unknown. Most decisions aren't like going through a traffic intersection, where we've all agreed to what the rules of the road are. We have this cognative chain saw that cuts off all the other possible branches of the tree and we're only left with the thing that happened. On top of that, as you talk about this kind of determinism problem, we also get hind sight by us. And they're related, which is, if something happens a particular way, we feel like we should have seen it coming. It had to be that way, that was the only outcome that could have occurred.
